Questions
Do I need a scanner?
No. A phone photo in daylight works. The cleanup makes grey or shadowed paper white and the ink dark.
My strokes look broken. What should I do?
Move the Ink threshold slider to the right so lighter strokes count as ink, or tick Darker ink. Signing with a darker pen helps most.
Is the signature cropped automatically?
Yes. The tool finds the ink, centres it and leaves a small margin. You can still drag and zoom.
Is my signature stored?
No. It never leaves your device and disappears when you close the page.
